Increased Energy Savings for Your
AUTOMATIC ENERGY-SAVING
FUNCTION
With its Automatic Energy-saving Function, the L300P delivers
“real-time” energy-saving operation for your fan and pump
applications. The function insures that motor operates at minimum
current in response to the torque required by the load.
ENHANCED INPUT/OUTPUT TERMINALS
Three relay output terminals are provided
as standard for flexible interface to external
control systems.
ANALOG OUTPUT MONITOR
In addition to PWM monitor(FM), programmable analog output monitors are also available for
both voltage(0
-
10VDC) and current(4
-
20mA) at AM and AMI terminals of the L300P.
INTELLIGENT INPUT/OUTPUT TERMINAL SYSTEM
The L300P features an intelligent control
terminal system, which allows necessary
drive I/O functions to be freely programmed.
Input terminals can be selected for either
sink or source type logic.

Eliminates control rewiring when field replacing the L300P.
The L300P’s compact size helps economize panel space.
Installation area is reduced by approximately 30% from
that of our previous series.
(Comparison of 11kW (15HP))
You can select frequently used commands and store
them for fast reference.
RS485 is provided as standard for ASCII serial
communication.

Windows
®
Operating System.
Output frequency can be controlled by the integral
potentiometer provided as standard on the OPE-SR.
The OPE-SR can be removed for remote control, and has

Disturbance voltage of the main circuit power supply and
of the control circuit power supply has been improved by
approximately 15dB( V) and 20dB( V) respectively compared
to our previous model(J300), resulting in significant reductions
to noise interference with sensors and other peripheral
devices.

200V Class
Up to 30kW.
An optional conduit box is required for 37kW to 55kW to meet NEMA 1 .
The protection method conforms to JEM 1030 / NEMA(U.S.).
The applicable motor refers to Hitachi standard 3-phase motor (4-pole).
To use other motors, care must be taken to prevent the rated motor current
(50Hz) from exceeding the rated output current of the inverter.
The output voltage decreases as the main power supply voltage decreases
except for the use of AVR function.
To operate the motor beyond 50/60Hz, please consult with the motor
manufacturer about the maximum allowable rotation speed.
Braking resistor is not integrated in the inverter. Please install optional
braking resistor or dynamic braking unit when large braking torque is
required.
Storage temperature refers to the temperature in transportation.
Conforms to the test method specified in JIS C0040(1999).
When using the inverter from 40º to 50ºC ambient, the output current of
the inverter must be derated (see the next section on derating curves).

400V Class
Up to 30kW.
An optional conduit box is required for 37kW to 55kW to meet NEMA 1 .
The protection method conforms to JEM 1030 / NEMA(U.S.).
The applicable motor refers to Hitachi standard 3-phase motor (4-pole).
To use other motors, care must be taken to prevent the rated motor current
(50Hz) from exceeding the rated output current of the inverter.
The output voltage decreases as the main power supply voltage decreases
except for the use of AVR function.
To operate the motor beyond 50/60Hz, please consult with the motor
manufacturer about the maximum allowable rotation speed.
Braking resistor is not integrated in the inverter. Please install optional
braking resistor or dynamic braking unit when large braking torque is
required.
Storage temperature refers to the temperature in transportation.
Conforms to the test method specified in JIS C0040(1999).
When using the inverter from 40º to 50ºC ambient, the output current of
the inverter must be derated (see the next section on derating curves).

(*1)
You can clear the error by pressing the Start / Reset key 10 seconds after the trip occurred.
(*2)
If an EEPROM error occurs, be sure to confirm the parameter data values are still correct.
When the built-in EEPROM memory has problems due to noise or excessive temper-
ature, the inverter trips and turns off its output.
When a malfunction in the built-in CPU has occurred, the inverter trips and turns off
its output.
When a signal to an intelligent input terminal configured as EXT has occurred, the
inverter trips and turns off its output.
The inverter is protected by the detection of ground faults between the inverter output
and the motor during power-up tests. This feature protects the inverter only.
When the input voltage is higher than the specified value, it is detected 60 seconds
after power-up and the inverter trips and turns of its output.
When instantaneous over-current has occurred, the inverter trips and turns off its
output to protect main circuit element.
When the thermistor inside the motor detects temperature higher than the specified
value, the inverter trips and turns off its output.
When the DC bus voltage exceeds a threshold, due to regenerative energy from
the motor, the inverter trips and turns off its output.
When a motor overload is detected by the electronic thermal function, the inverter
trips and turns off its output.
The inverter output was short-circuited, or the motor
shaft is locked or has a heavy load.
These conditions cause excessive current for the
inverter, so the inverter output is turned off.
When the regenerative braking resistor exceeds the usage time allowance or an over-voltage caused by the
stop of the BRD function is detected, the inverter trips and turns off its output.
A decrease of internal DC bus voltage below a threshold results in a control circuit fault. This condition can
also generate excessive motor heat or cause low torque. The inverter trips and turns off its output.
If a strong source of electrical interference is close to the inverter or abnormal operations occur in the built-
in CT(Current transformer), the inverter trips and turns off its output.
An error occurs when power is cycled while the inverter is in RUN mode if the Unattended Start Protection
(USP) is enabled. The inverter trips and does not go into RUN mode until the error is cleared.
When power is cut for more than 15msec., the inverter trips and turns off its output. If power failure contin-
ues, the error will be cleared. The inverter restarts if it is in RUN mode when power is cycled.
When the inverter internal temperature is higher than the specified value, the thermal sensor in the inverter
module detects the higher temperature of the power devices and trips, turning off the inverter output.
Gate array error
Communication error has occured between CPU and gate array.
Due to insufficient voltage, the inverter has turned off its output and been trying to
restart. If it fails to restart, it goes into the under-voltage error.
